The image shows a woman identified as Naya by E! News, holding the arm of the actress’ fiancé Big Sean as he escorts her out of waters.

And the ample cleavage the woman sports in a black bikini top is now rumoured to be the result of a breast augmentation.

Naya simply captioned the photo “Beach days…” but didn’t provide any further information.

Within minutes, the image had garnered thousands of likes.

“…A boob job obviously lol,” one commenter wrote.

E! noted in its report the curves could have been the result of lighting or the angle at which the picture was taken.

Naya had yet to respond to her fans’ suspicions about a surgery at press time, but the actress was busy preparing to celebrate her show’s 100th episode Tuesday night.

“’Being a part of something special makes you special.’ Glee has and continues to be one of the most special journeys in my life," she tweeted. "Thank you to the fans, crew, producers, directors, 20th, and most importantly the cast for making these 100 episodes truly magical. Enjoy!"

Naya previously spoke about her gratitude over being a part of the hit TV musical since 2009.

"She can do anything. That's the beauty of Santana,” she told E! last fall about the joys of playing her character Santana.

"We always kind of knew that [Glee would end]. We've had an amazing run on this show, and so whenever it ends, it has to end. Unfortunately, it can't go on forever. But, I'm just really grateful that I was on it for this long."
